description

This 436-3321 is stepped forged steel flange adapter. One side matches crankshaft flange of C27/C32, the other provides threaded holes for 434-6573 viscous damper. It transfers torque and corrects bolt pattern mismatch to keep damper concentric. Each adapter is heat treated, crack inspected and face runout tested. It is a dedicated transition part for C27 and C32 engine viscous damper assembly.

Part No.：436-3321
Name：CAT Damper Adapter
Material: Gray (Flake) Iron

Advantages

1. Forged alloy steel, high torsion fatigue resistance under cyclic heavy torque
2. Precision machined face for good concentricity and less resonance risk
3. Dedicated bolt layout for 434-6573, direct fit without on-site modification
4. Distribute clamping load, protect crank flange from damage

FAQ 

Q1：Can 436-3321 interchange with 245-3508 adapter?
A：No. Flange size, bolt pattern and matched damper type are different.
Q2：Is this a Reman part?
A：No. It is brand new OEM forged steel adapter.
Q3：What failure will occur if damaged adapter stays in service?
A：Eccentric viscous damper, severe low-frequency resonance, crank flange crack and bolt fracture.
Q4：Should I inspect the adapter while replacing viscous damper?
A：MPI inspection is required. Replace if threads or face distorted to protect new damper.
